In a time when data has become a highly valued commodity within many mining and quarry operations, managing large amounts of current and historical information can be difficult. If not managed properly, trying to leverage the data to make informed operational decisions promotes another challenge. Geographic Information System (GIS) is an environment that uses computers and software to create, manage, analyze, and map all types of data. Currently, the mining industry is faced with a challenge to produce the demanded critical metals and minerals that drive our economies. GIS is leveraged in many large mining industries today to help drive decisions, save cost and plan for future operations. Specifically in the Drilling, Blasting and Quarrying industries, data is being captured at many different levels, whether it is a subsurface geological, blast performance, quarry surveys, loading and hauling, or crushing performance. Pen and paper logs and reports compiled lack the dimension that GIS can bring for extracting value from real-time or historical data. GIS connects data to maps, integrating location data with all types of descriptive information. Paired with Artificial Intelligence, additional analytical layers can be built on platforms to extract data and automate workflows. Having the ability to encompass several forms of collected data to drive operational decisions can bring huge savings to the bottom-line. This paper will dive into the areas where GIS data can drive value into operations by assisting in the management and analysis of the types of data being captured, specifically with Drill and Blast. Whether it is tracking haul road conditions, monitoring locations of equipment, environmental conditions, quantifying blast performance or developing a quarry plan based on geological models. GIS can collectively encompass all of this data to bring tremendous value to the operations, improving safety, efficiency and production.

O & G Industries, Inc. owns and operates a number of rock quarries within the State of Connecticut. These rock quarries are surrounded by residences and commercial neighbors who have concerns related to blasting. In addition, local commissions which issue the mining permits to O & G are required to hold public hearings, prior to issuing the annual permits each year.

Recent trends in blasting engineering and its related fields, at the level of professional academia, have tended to exclude detailed discussion and examination of the formative experiences of the engineering student. In particular, the extra-curricular aspects of the undergraduate program in engineering—focused, in this case, on the summer job—will be shown to contain a wealth of heretofore underappreciated knowledge in the field. In Surveying the Damage: Post Traumatic Stress and Pre-Blast Surveys, I intend to outline and examine some of the more unusual experiences afforded me by my work as a preblast surveyor in the summer of 2007. In this capacity, I was required to make a visual note of existing conditions of surrounding residential and commercial structures within 100 m (328 ft) of two separate blasting sites in central-east Ontario. In the interest of both convenience and specificity, I have attempted to organize the paper as a crossdiscipline survey of the field according to the conference’s list of suggested topics. In the paper’s first section, I will discuss the topic of Environmental Improvement and Remediation by using a case study in which not one, but two dead cats were found during the course of a routine pre-blast survey. The second section will undertake a discussion of on-site blaster gossip as an entry point into a wider discussion of Workplace Communications Management. In the paper’s final section, I will detail an early morning encounter with a 300 lb, stark-naked trailer park inhabitant as a cross-sectional analysis of the topics of Drilling in Hostile Environments, Vibration and Seismology (Sizemology?), Ethics in Blasting, Crisis Management, Risk Assessment and Public Relations. It is my hope that this paper will begin to open up a critical space for discussion of the formative experiences of engineering students during the undergraduate university program in terms of their far-reaching effects on later performance within the industry.

"An Event Tree Analysis (ETA) is an established approach for logically deconstructing and assessing scenarios for probabilistic risk assessment. This deconstruction into a series of understandable eventsfacilitates probability estimation for explicitly defined explosive terrorism scenarios with consideration of modes of possible failure during execution (a scenario is defined through selection of a target, selection of an explosive material, and interdiction prior to arriving at general target location, etc.). Further, each event is decomposed into a range of possible outcomes. The physical action or reality ofthe outcome is statistically represented by “branches” of the event tree (e.g., the terrorist may choose totarget a stadium, hotel, or subway; terrorists may be successful or unsuccessful in acquiring the material)."

The recruitment and retention of future talent into the explosives industry is becoming increasingly important. Student chapters help with this effort but what are they doing and are there things they could learn from each other? This paper discusses the University of Kentucky Student Chapter's efforts to grow membership, retain its recruits, and integrate them into the explosives industry. Several social and professional events during which the students are able to meet and network with members of their future industry are introduced. The special relationship that has been fostered between the University of Kentucky and Missouri University of Science and Technology is discussed. Professional development initiatives which are critical for a student to become vested in the industry are shared in this paper. These opportunities which range from internships to research positions allow a person to get a better understanding of the explosives industry and find the niche that best suits them. Many of the student chapters are closely connected with engineering programs. While this makes sense and both entities benefit from these arrangements there is a trend of job placement primarily in the engineering industry. By providing these students with the chance to learn more about the explosives industry and get hands on experience more of these future engineers and professionals can be retained after their graduation.

Explosives techniques and technology are constantly evolving and improving, yet basic communication and business skills are not being used regularly. Many potential blasting projects never occur due to simplistic, basic factors, such as a lack of communication. Articulate communication is the key component in the blast approval process, which has changed remarkably from how business was conducted fifty years ago. Imperative to the approval process is communication outlining the safety and benefits of the blasting project.
